View-based ingestion pipeline at internal/fullhistory/ingest: - HotIngester / ColdIngester interfaces over xdr.LedgerCloseMetaView. - Six ingesters (ledger/events/txhash x hot/cold) using the #764 view extractors; hot stores injected (daemon-owned), cold writers per-chunk. - Per-tier HotService (parallel per-LCM fan-out) / ColdService (sequential + Finalize), config-driven data-type selection. - MetricSink interface + Prometheus implementation (daemon convention); per-ingester + aggregate signals, emitted on success and failure paths. - ChunkSource abstraction: pack / GCS / S3 / any datastore, extensible. Hardening: drain validates per-ledger LedgerSequence; txhash cold .bin published atomically (tmp+rename); concurrency-safe txhash cold reader; failure-path + .bin-content tests. Bundles the txhash cold-store extraction (a #765 dependency). Closes #765.

Implements #765 — the full-history ingestion path. Code at
